motor brakes
(OP)
I'm fighting a couple brakemotors, made in an eastern asia/pacific rim country, and with little documentation available,,, none in any language I can understand. I've worked with/on quite a few motor brakes in the past on NEMA motors, but my memory of the details is poor. Anyone have any good links / urls or other electronic documents pertaining to general repair/adjustments of motor brakes?
This is on a hoist traversing application, integral horsepower.

Reliance also has manuals for other models here:

Look in the "manuals" section.

Brakes are not fit-and -forget items, we see many that have failed. I think what is important is that regular checks are made on the brake itself. Things to be aware of are the build-up of dust from the friction material that can prevent free movement and operation, and the monitoring of the airgap and friction disc thickness as it wears. I have also seen a few where the supply leads for the brake have come into contact with moving parts and caused earth faults and O/Cs

StarD, integral Hp is quite large machine employing brake motor is quite complicated. However, when it comes to Demag, i'm hesistant about tapered rotor and core works with integral machine. Although principles applies commonly to all hoisting system in all mechanical aspects.
We have hoisting system utilizes separate braking system we call it "magnetorque motor brake" it is electrically operated so wear and tear is out on the subject.
RE: motor brakes
Perhaps we could be more helpful if you posted the make/model etc from the nameplates.

were not very helpful wrt brake adjustments, but they make the wiring clear enough ... for some Sumitomo brakemotor, not necessarily yours.
Maybe it will lead you to something better.
